Witteveen+Bos awarded tender for engineering component of pumping station in WarmtelinQ project
In November 2021, consultancy and engineering firm Witteveen+Bos was awarded the tender for the (detailed) engineering component of the Delft pumping station, part of the WarmtelinQ heating project in the province of South Holland. The size of the main transportation pipeline, the length of the route and the source of the heat make this a unique and large-scale heat recovery project in the Netherlands. Winning this tender also means that Witteveen+Bos has been selected for the framework contract for the design of the above-ground infrastructure for the project.
WarmtelinQ is the world’s first open main transportation pipeline for heat and aims to provide households and businesses between the Port of Rotterdam (via Vlaardingen, Schiedam, Midden-Delfland, Delft, Westland and Rijswijk) and The Hague with affordable, reliable and sustainable heat. An ‘open’ transportation pipeline means that anyone is allowed to use it – under the same conditions. The pumping station in Delft is an indispensable link in the WarmtelinQ network. It will provide sufficient and constant pressure in the transportation pipes, allowing waste heat from industrial premises in the Port of Rotterdam to be supplied to approximately 150,000 households between Vlaardingen and The Hague.
Delft pumping station
The WarmtelinQ network consists of supply and return pipes. The supply pipe transports hot water to the heat distribution network in The Hague, and the return pipe carries the (cooled) water back to the heat source: the Port of Rotterdam. To accommodate this, a pumping station with the capacity to pump over 4,000 tonnes of water per hour will be built in Delft. Various challenges are associated with the length of the route, the ‘open’ nature of the main transportation pipeline and the ultimate size of the underlying heat network. These include the correct integration of technology and keeping the heat supply affordable. Together with partner Qirion, Witteveen+Bos will be involved in the project until its completion in 2024.
‘A robust network is necessary for efficient and reliable large-scale distribution of (renewable) energy, regardless of the form. From our office in Rotterdam, we’ve been involved in the engineering component of transporting waste heat from industry to WarmtelinQ's main transportation pipeline since 2018. Partly due to our experience and our well thought-out action plan, we’ve now been selected as the official engineering partner. We’re proud of that,’ explains Robert Kools, project director at Witteveen+Bos. ‘We want to use our expertise and drive to support clients with complex (energy) issues and so make a positive contribution to the Netherlands’ climate objectives.’
Guido Custers, project director at WarmtelinQ: ‘This project is important because it will give the energy transition in South Holland and the climate ambitions in the Netherlands an enormous boost. We’ve never seen that with heating on this scale before. It’s great that we can collaborate with expert partners like Witteveen+Bos. With WarmtelinQ, Gasunie is using its infrastructural knowledge to accelerate the energy transition as an independent network operator.’
About WarmtelinQ project
More than half the energy used in the Netherlands is for heating, of which almost half is used to heat homes and businesses. The WarmtelinQ project aims to use waste heat from industry (which is currently lost into the air) to provide homes and businesses between Vlaardingen and The Hague with heating. The waste heat is transported by means of hot water through a transportation pipeline, replacing natural gas as a source of heat. This makes the WarmtelinQ project an important step towards a carbon-neutral energy supply by 2050. Currently, the permits required for WarmtelinQ are with the relevant authority. If the plans go ahead, work will commence in 2021. In the future, other sustainable heat sources will also be connected to WarmtelinQ – for example, heat obtained from water, soil or other sustainable sources. WarmtelinQ is a Gasunie project, carried out in collaboration with the Port of Rotterdam. For more information, visit www.warmtelinq.nl
